Small-sized business information management will be vitalized by cost reduction of APP development and using former infra instead of extra expert.
Because of these causes, the promotion of information management of SME is deterred, the problem of reduction of corporate competitiveness and efficiency of management has occurred.
The developer requests what they need to produce APPs, and the enterprise cooperate to serve requested data for the efficient development.
Even though each APP is made separately, we unify some variable’s data type for connection between APPs for the future.

Reduction of the GaO6 octahedral tilt proved effective for oxide ion conduction.
For structural analysis of these samples, time-of-flight neutron powder diffraction data were collected at room temperature, 300, 500 and 800°C using the 90-degree banks of the Sirius diffractometer [10] at the High Energy Accelerator Research Organization in Japan.
The diffraction data collected were analyzed by the Rietveld method using the RIETAN-TN program [11-12].
This reduction of octahedral tilts in LSGM was due to shortening Ga-O bond lengths [8-9].

By analyzing the data acquired trough pyrometers, many companies realized how many defects are related to excessively high exit temperature thus limiting production rates and consequently productivity.
K-type thermocouples of 1500mm length and 1 mm diameter were used for the thermal monitoring and the data were continuously acquired by means of an Agilent acquisition system connected to a laptop (figure 4).
Ten AA6060 billets were deformed at 2,71mm/sec of ram speed during the trials: three billets were initially extruded for homogenizing the temperature of the system without the use of the nitrogen, then three more billets were processed in the same conditions in order to evaluate the repeatability of the acquired data and finally four billets were extruded with the use of nitrogen die cooling.
The strongest reduction happened in proximity of die inlet (sensor 5): this is probably also in relation with the shape of inlet channels that promotes a higher nitrogen flux in the bottom part of the die; the second most sensitive location is thermocouples 3 that expires a reduction lower than thermocouples 5 but still significant.
On the profile, such reduction generated conditions comparable with billet 6 ones.

According to literary data, the treatment of such fractures is not effective enough, which leads to a prolongation of rehabilitation periods and disability, especially among patients of older age groups.
Data analysis was carried out only on officially published sources.
Available data on three- and four-fragment fractures indicate the possibility of a violation of vascularization of the humeral head, dislocation and cartilage damage with subsequent necrosis of the head and collapse, which is observed in 30-100% of cases.
Also, there is not enough reliable data on the treatment of ipsilateral fractures of the humerus, at the level of the proximal and diaphysis.
Open reduction and internal fixation of proximal humeral fractures with use of the locking proximal humerus plate.

Introduction The attainments of high performances combined to the contemporaneous mass reduction of components contributed to a very fast and wide development of the market of aluminium cast parts, especially for what concerns the automotive field.
The goal was to optimize the heat treatment process, taking advantages from the reduction of treatment times.
Even if, considering the results of single tests and the standard deviation values, it was clear that the newly proposed and shorter heat treatment cycles (A and B) cause higher dispersion of the obtained data with respect to the conventional one and in few samples the tensile properties being very close to the minimum target value.
The highest dispersion of data related to the mechanical properties can be justified when considering the microstructure features, as it is evident in figure 2, where the microstructure features of conventionally and of A1 treated samples are compared.
The new cycles allow high reduction of the treatment duration with consequent economical advantages.

In the previous study [1], it was revealed that the absorbed hydrogen caused a remarkable reduction of ∆Kth in hard low alloy steel.
Each specimen was fatigue tested under different nominal stress amplitude and fatigue crack propagation property was obtained by gathering all data.
The data were obtained in short crack region in the range of 0.03 - 0.2 mm.
The relationship between the reduction of ∆Kth by hydrogen charge and HV is shown in Fig. 5.
There were no reductions of ∆Kth by hydrogen charge in soft materials whose HV were lower than HV = 200.
